Grove Mountains 021992 (GRV 021992)        72° 46' 31"S,  75° 20' 48"E

Antarctica

Found: 20 January 2003

Classification: Carbonaceous chondrite (CV3)

History: Y. Ju recovered this stone on a moraine in Grove Mountains, Antarctica. It weighs 1.1 g and has an irregular shape. Part of a black fusion crust remains.

Petrography: (A. Zhang, PMO) The meteorite contains ~40 vol% chondrules. Some chondrules are large (up to ~2 mm). Porphyritic olivine chondrules are dominant. Calcium-aluminum-rich inclusions commonly have melilite-dominanted mineral assemblages. Matrix is very fine-grained and mainly composed of fayalitic olivine. Metallic Fe-Ni and sulfides are relatively rare and most of them were weathered. Some olivine fragments show chemical zoning.

Geochemistry: (A. Zhang, PMO) Olivine (Fa2.1-55.7, average=Fa13.6±14.6), and low-Ca pyroxene (Fs1.1-3.2, average=Fs1.7±0.7; Wo0.4-7.7, average=Wo1.50±2.1).

Classification: Carbonaceous chondrite (CV3)

Specimens: All of the sample mass and a polished thin section are on deposit at PRIC.
